Rigid Compression and Set Screw Connectors and Couplings connect and bond threadless rigid
or intermediate metal conduit to a box, enclosure, or to couple ends of threadless conduit.
The Industrial Hallmark
Inside this section
• Heavy wall industrial grade Rigid Compression Connectors
and Couplings carry UL Rain Tight and Concrete Tight listings
through the 2” trade size.
• 2-1/2” to 4” carry a concrete tight rating.
• Connectors with insulated throats meet and exceed all code
requirements. Insulators with shield conductors prevent
thread damage, and reduce the wire pulling force required.
• Set screw fittings utilize captive screws that will not loosen
with vibration.
• Rigid Set Screw Connectors and Couplings are all concrete
tight when taped.

• The true value and significance of these fittings lies in their
versatility. Field threading is assured in hostile and hazardous
locations.
• Rigid Compression and Set Screw fittings are ideal for use in
new construction as well as maintenance and repair.

Breadth of Line
• Reducing Bushings – UL listed for use in Hazardous
Locations. Precision – machined steel assures mechanical
protection of the raceway. Available in either tapered or
straight threads, steel or aluminum.
• Chase Nipples – Precision machined, designed to couple
boxes back-to-back.
• Three piece (Erickson) Couplings – Designed to bond ends of
threaded conduit when neither length of conduit can be
rotated. Certified Concrete tight; 1/2" and 3/4" trade size are
rated Liquid Tight.
• Combination Couplings – Unite EMT to Rigid/IMC. 1/2" and 3/4"
trade sizes are rain and concrete tight.
• Conduit Locknuts – UL and CSA listed. Superior steel
construction and sparkling zinc finish.
• Sealing Locknuts – Provide a positive rain tight seal against
water and other liquids. Locknuts can be used with sheet or
cast enclosures, or in place of a threaded enclosure connector.
• Grounding Locknuts – To insure a positive bond and for
installations where severe vibration is encountered.
• Conduit Hangers – To fasten and secure EMT or rigid conduit
to a threaded rod or mounting surface.
• Rigid Steel Straps – To fasten and support rigid or intermediate
conduit to a mounting surface.
• Reducing Washers – To reduce knockout size on sheet metal
boxes or enclosures
